Reaction Steps

A mixture of 2.7 parts of 3-(2-ethoxyethyl)-2-(1-piperazinylmethyl)-3H-imidazo [4,5-c]pyridine, 2.7 parts of 1-(2-bromoethyl)-4-ethyl-1,4-dihydro -5H-tetrazol-5-one, 1.3 parts of sodium carbonate and 72 parts of N,N-dimethylacetamide was stirred overnight at 70° C. The reaction mixture was poured into water and the product was extracted with dichloromethane. The extract was dried, filtered and evaporated. The residue was converted into the ethanedioate salt in 2-propanol. The salt was filtered off and dried, yielding 3.9 parts (64.0%) of 1-[2-[4-[[3-(2-ethoxyethyl)-3H-imidazo[4,5-b]pyridin-2-yl ]methyl]-1-piperazinyl]ethyl)]-4-ethyl-1,4-dihydro-5H-tetrazol-5-one ethanedioate(1:2); mp. 170.9° C. (compound 38).
